Examples of the data collected to test the feasibility of the top workflow of Fig. 1 . Individual gene product samples from the Pyrococcus furiosus genome were loaded into a 5 × 5 spatial array of 3 µL samples (middle left). A single raster scan was used to monitor both Ni (lower left) and Zn (upper left) Kα emission, identifying the presence of these metals in the indicated wells. Ni XANES speciation (lower right) clearly differentiates the types of Ni binding sites and Zn EXAFS structural analysis (upper right) shows the sensitivity available for determining metal-site structures. The element maps and XAS data were collected on beamline 9-3, SSRL (SPEAR 2), using a 1 mm × 1 mm focused beam and 30-element intrinsic germanium detector. |
